Integrated Power Distribution Cabinet: Key Features & Typical Use
One Enclosure Instead of Three
A pole-mounted or pad-mounted distribution point traditionally needs separate provision for transformer protection, metering and capacitor compensation. The JP integrates all three functions in a single weatherproof stainless steel enclosure, which reduces the number of joints, the amount of site work and the number of places where water can eventually get in.Six Models Matched to Transformer Rating
The range covers transformer capacities from below 50 kVA up to 500 kVA across six models, from 650 x 700 x 350 mm for the smallest rural transformer to 1550 x 1200 x 700 mm for a 500 kVA unit. Because capacity and enclosure size move together, the cabinet is not oversized for a small transformer or cramped for a large one.Weather Protection for Remote Sites
A double-slope rain cap and built-in sealing strips keep water, rain and dust out of the enclosure, while ventilation holes on the side faces allow compensation and protection losses to leave the cabinet by convection. These are rural and semi-urban substations where maintenance visits are infrequent, so the enclosure has to work unattended.Thermal Stability Under Varying Load
Distribution transformers and capacitor banks work through load cycles that change temperature inside the cabinet. Side ventilation keeps the internal temperature stable under those fluctuations, which protects the accuracy of metering and the life of contactors and protection relays rather than only keeping the enclosure within a rating.Integrated Power Distribution Cabinet Specifications & Technical Data

JP — Integrated Outdoor Distribution Cabinet for Transformer Substations
At the end of a rural feeder or on a pad in a housing development, a distribution point has to protect the transformer, measure what passes through it and correct the power factor, all in a location nobody visits often. The JP does all three inside one 201 or 304 stainless steel enclosure, which removes the extra joints and site work that separate enclosures would require.This equipment is also searched for as a JP integrated distribution box, a pole-mounted distribution cabinet or a rural distribution transformer box, and it is compared with separate protection, metering and compensation cubicles. Integrating the functions removes the joints between enclosures, which is where outdoor distribution points usually fail, so the practical question for a utility buyer is whether the internal protection and metering can be assembled and tested as one unit before dispatch.Six models track transformer capacity from below 50 kVA to 500 kVA, from a 650 x 700 x 350 mm cabinet up to 1550 x 1200 x 700 mm. A double-slope rain cap and built-in sealing strips keep water, rain and dust out of the enclosure, and ventilation holes on the side faces let compensation and protection losses leave the cabinet by natural convection.Inside, breakers, current transformers, monitoring instruments and protection relays mount on a detachable base plate. The cabinet is used for outdoor distribution transformer stations and rural grid upgrading projects, and accepts knockouts, custom printing and complete-set assembly with the component brands your utility or project specifies.Factory-Direct Integrated Power Distribution Cabinet Manufacturer & OEM / ODM

Integrated Power Distribution Cabinet Buying Guide from the Manufacturer
The JP is specified from the transformer rating and the protection scheme, not from the enclosure alone. These are the points we confirm.
- Confirm the transformer capacity so the correct model is selected from the six available.
- Confirm the protection, metering and capacitor compensation equipment to be integrated.
- Confirm the pole or pad mounting arrangement and the incoming and outgoing cable directions.
- Confirm the environment to select 201 or 304 stainless steel and the required protection degree.
- Send the single-line diagram, transformer datasheet and site photographs.
- Approve the drawing, then production with inspection and dispatch.

What is an integrated power distribution cabinet?
It is an outdoor enclosure that combines several functions of a distribution substation in one body: transformer protection, metering and capacitor compensation. The JP is fabricated from 201 or 304 grade stainless steel in six models covering transformer capacities from below 50 kVA up to 500 kVA, with a double-slope rain cap and side ventilation.What is a JP cabinet used for?
It is used at distribution transformer substations and grid distribution nodes, mainly on rural and semi-urban networks and in rural grid upgrading projects. It protects the transformer, measures what passes through it and corrects the power factor at the point where the load is, which matters where maintenance visits are infrequent and each separate enclosure would be another place for a fault to develop.What is the difference between a JP cabinet and a normal distribution box?
A distribution box distributes circuits; a JP cabinet replaces the functions of several separate outdoor enclosures at a transformer station. It integrates transformer protection, metering and capacitor compensation in one weatherproof body, and its size follows the transformer rating — from a 650 x 700 x 350 mm cabinet below 50 kVA up to 1550 x 1200 x 700 mm for a 500 kVA unit.Who manufactures integrated distribution cabinets?
Because this equipment combines protection, metering and compensation, it is normally bought from manufacturers who also build switchgear and can assemble and test the internal equipment as a set rather than supplying an empty enclosure. Ask whether the internal assembly is tested at the factory, which protection and metering brands can be specified, and whether the enclosure is stainless steel throughout. LYE manufactures and assembles the JP in Wenzhou and holds ISO9001, ISO14001, ISO45001, CCC, CE and TUV certification.How much does an integrated distribution cabinet cost?
Indicative factory-direct pricing is roughly US$300 to US$3,000 per cabinet, depending on the transformer capacity, the protection and metering equipment selected, the capacitor compensation arrangement and the quantity ordered. Because the cabinet is priced with its internals, the transformer datasheet and protection scheme are the documents that convert an indicative band into a firm factory-direct figure.

Use a distribution box for final circuits and compact branch protection; use a cabinet when the project needs larger incoming capacity, more feeder groups, metering, busbars or greater internal separation. The final choice should be checked against the single-line diagram, device list, available installation space and local project rules.
Provide the device schedule, circuit quantity, component dimensions, cable-entry direction, mounting method and required spare capacity. LYE also reviews door clearance, bending radius, heat-producing devices and the usable depth behind the mounting plate before confirming an enclosure size.
Start with the actual exposure to dust, rain, cleaning water and accidental contact rather than choosing the highest number by default. Cable entries, ventilation, door seals and installation workmanship affect the finished assembly, so the target rating and verification basis must be confirmed for the specific product and project.
Coated or galvanized steel is commonly considered for general indoor service, stainless steel for humid or corrosive locations, and engineering plastic for lightweight non-metallic applications. Material grade, thickness, UV exposure, chemical contact and earthing requirements must be confirmed against the installation environment.
Share the component heat load, ambient temperature, solar exposure, duty cycle and allowable internal temperature. LYE can then review enclosure volume, spacing, ventilation or fan provisions, sun shields, heaters or drainage details; the final thermal design remains tied to the installed equipment and site conditions.
Yes. A dimensioned drawing is preferred, but a physical sample and clear reference photographs can also start the review. Material, thickness, openings, hardware, finish, labels, inspection points and packing are recorded before sampling or repeat production.
PDF and common 2D CAD drawings are suitable for most enclosure enquiries, while 3D files can help with complex assemblies. Include a revision number, units, tolerances and component references; file compatibility and any missing production information will be confirmed during review.
A sample or first article can be arranged for a new or customized product. The approval plan should identify dimensions, openings, fit, appearance, hardware, labels and packaging, together with the sample cost and timing agreed for the actual order.
Available documents may include approved drawings, packing lists, dimensional or appearance inspection records, product data and certificates applicable to the confirmed model. Destination-specific declarations or third-party testing must be requested before order placement so availability and scope can be verified.
Lead time is confirmed after the product scope, quantity, sample requirement and finish are known. Packing is reviewed against product weight, surface protection, destination and shipping method; if an issue is found after delivery, send the order reference, label, photographs and quantity affected so it can be traced and reviewed.
